Continuation of application Serial No, 875,857, ril d Decemb 7, 1914This application filed ch r 1916. 'Serial No. 35,192, r a v To all whomit may concern:

Be it known that I, EDWIN PRESCOTT, a citizen of the United States,residing at Arlington, in the county of Middlesex and State ofMassachusetts, have invented an' Improvement in Shutter-OIperatingDevices, of which the following is a specification.

This invention relates to shutter-operating devices adapted to beactuated by means accessible at the interior of a building, and embodiesmany of the features of, and is intended as an improvement upon LettersPatents granted to inc, #816,881,- dated April 3, 1906, and #992,449,dated May 16, 1911, and is a continuation of my application, filed Dec.7, 1914:, Serial Number 875,857.

The present invention has" for its object the provision of anoscillating swingingmember adapted to be connected with a turning shaftor member and arranged for connection with a bearing-plate on theshutter,

with its axis of rotation in approximately parallel relation with thevertical plane of the shutter, and its center of motion in verticalalinement with the upper hinge, so that the device may serve as a hinge;also the provision of a housing on the bearing-plate arranged to receivethe oscillating swingingmember, which is made adjustable, thereby tohold said member in different positions more or less removed from theshutter to accommodate reveals of various depth; also the provision ofmeans for connecting the bearing-plate with the shutter, which ad- 'mitsof a transverse adjustment thereof with respect to the shutter, wherebythe oscillating swinging-member may be held in proper relation with thehinge or hinges of the shut- I ter and also admits of angular movementon and with respect to the shutter, so as to obtain the desired tensionof the handle on the fastening-pin; also to construct an oscillatingswinging-member comprising a yoke and a short spindle extended at rightangles from the crown of the yoke, said spindle being adapted to besupported by the housing on the bearin -plate and arranged with itslongitudinal-axis in parallel relation with the vertical plane of theshutter; also the provision of a housing adapted to receive the spindleof the swinging-memher and to hold said spindle against angular andlongitudinal movements with respect th rewe w in a predetermined PO"sition, in which position the housing may various parts of the countrythe reveals are.

The turning-memberor shaft 1, is adapted to receivea handle 1 at oneend, and has at its other end an angularly formed end-po tion '2. Saidshaft has its bearings in' a V bracket 3, which is adapted to beattached to the outside of the casing by pins or nails' i,

whereby it maybe disposed at different distances from the casingaccording to the depth of the reveal. Said shaft is adapted foroscillation about a longitudinal aizis,

whereupon. its end-portion 2 is corresponding r -P i ,l tes1- I rightangles from-the middle of'its crown,

; holes in said arms and projectbeyond said 7 which spindle has itsbearings in the bracket 3, being disposed at about a angle from theperpendicular; Ajblock 7 V is arranged between the arms of the yoke 5,and has journals at itsends which extend through arms; The angularlyformed end-portion 2 of the turning-shaft is loosely connected orswiveled to said block 7 by a pin 8, here shownas arranged on the block.

The oscillating swinging-member consists of ayoke 10, having ashortspindle 12, extended at right angles from the middle of its crown. Thearms of said yoke 10 are spaced apart sufliciently to receiveibetweenthem the yoke5, and they are pivotally connected with said yoke, theprojecting ends of the journals at the ends of. the block 7, whichextendthrough arms of the yoke 5 entering sockets formed in the arms ofthe yoke v10, see Fig. 6, and serving as pivots Through the medium ofthe yoke 5 and block 7, the oscillating swinging-member is con nected'with the turning-member or shaft 1, and is adapted to beswung in anapproximately horizontal plane, and whileso swung to be oscillated aboutits longitudinal axis.

115 represents a bearing-plate,see Figs. 1, 3, and 4, which hastransverse slots 16 designed to receive bolts or screws 17, by which itis attached to thejshuttcr, and is adjustable transversely with respectthereto, so that the .to; the bearing-plate.

parts supported by it may be arranged substantially 1n verticalalinement with the axis of the hinge or hinges of the shutter; and

also by means of said slots, said plate may a be adjusted angularly sothat the tensionof the turning-shaft and the engagement of its handlewith its fastening pin 1 may be varied. Said bearing-plate has a housing20 for the short spindle 12 of the oscillating swinging-member. whichhousing is or may be made adjustable in and out with respect As hereshown, see and 4, thehousing has two holes through it, arranged inparallel relation,

' which receive pins 21, projecting from the bearing-plate, and saidpins are made to tightly or frictionally engage the housing, so that thehousing will be held in different positions it may be set with respectto the bearing-plate. In lieu of this means for ad justably connectingthe housing with the bearing-plate, any-other means maybe em- .ployed,althoughv in so far ascertain features of my invention are concerned,the

housing need not bemade adjustable. The bearing-plateis hereshownattached; to the :inner stile of the shutter in'a perpendicularposition, or at least the housing 20 is so positioned, but it can beadjusted to other than a perpendicular position. 7 V '65 hole through itfor the cylindricalspindlel 1.2, which hole is arranged horizontally orthereabout and in substantially parallel'relation with the plane of theshutter, and said spindle, while very short, is still made long enoughtoextend entirely through said hole,

asrepresented in Fig. 1., In the form of houslng here shown, its outerend-portlon comprises two semicircularportlons 25 25,

arranged side by side, with narrow space betweenthem, and the'transversehole extends for substantially half its dlameter nto sa dsemicircularportions, as represented in Fig 7., The spindle 12 hasarrangecl' on it intermediate its length a single toothor pro-.

tooth 26, willbe arranged in the space between the portions 25. Atransverse groove 28 is formed in the housing coincident with the spacebetween said" portions 25,- of a depth corresponding with. the length ofsaid projection 26. This provides for the spindle 12 entering thehousing when its tooth 26 is in alinement withthe slot 27, and for beingthereafter turned with respect, to the housing, the tooth'moving in thegroove or in the space between the semicircular portions 25, accordingto its relative position to the housing. This slot and groove constitutea form of bayonet-slot whichpermits the housing to engage the spindlewhenin a predetermined position only, and vto be held by the housingagainst longitudinal movement-in all other positions. The positions ofthe slot in the housing and the tooth on the spindle. are arranged withrespect to each other, so that the'housing may be withdrawn from thespindle when the shutter-is in half-open position, as in such.

position it may be easily attached and detached. The spindle 12 is heldby the housin from moving angularlv and longitudinally, so that duringits full swinging movement it is forced to occupv the same plane,
